Allow creating modules with multiple entry points? #10

Or ... maybe not. GLSL modules have one entry point, so we'd exclude compiling to GLSL. At the least wait until we know if WSL supports this too.

Pro's:

Better code-reused at the GPU, so a tiny GPU memory consumption benefit?
Might be nice if it can be used to pack a vertex and fragment shader into a single module. But not sure if it can?
...

Why?

almarklein commented 4 years ago

SpirV and WSL support it. But yeah, maybe this is mainly to allow writing multiple shaders in a single file. We already allow that (e.g. using the decorator multiple times on a function). So it could well be that there is no benefit.

Edit: That's why the title of this issues ends with a question mark :)
